[DMCForum] Re: Testing Frequency valve

["cruznmd" <racuti1@xxxxxxxxxxxx>]

My book's in the car. I need a pocket bible to carry.

Ok, I'll tell you another story (it may not apply to you). I bought a 
new RPM relay and I still didn't have lambda. Why? One of the 
contacts in the relay was bent just enough that when the winding 
energized, only the fuel pump contact closed, not the lambda too.

The result? I heard the "click" but had no freq valve.

Yes, it gets it's power from the ECU. If you unplugged the ECU, no 
freq valve.

Put a dummy probe on the freq valve plug. Don't -assume- you have 
power. Assume means "(make an) Ass (out of) u (and) me". $5.00 at the 
most. :)
